KIT F-300 SENSOR/SWITCH 1.0”P, 1.25”P & 1.0”T-2.0”T

Catalog Number: F-300SL


Optional Flow Switch / Sensor is designed to detect Flow / No Flow.
A rare-earth magnet is located within the red PVDF float of the new F-300 flowmeters. When the magnet passes through the Alarm Trigger Zone of the Sensor Accessory, the built-in contact closure switch sends a signal to external devices.
Note: Two alarms can be placed onto one meter to obtain both ‘Flow Switch’ and ‘Flow Sensor’ capabilities. See diagrams below.
